This is the README.TXT file for the replication archive for: 

Levendusky, �How Does Local TV News Change Viewers� Attitudes? The Case of Sinclair Broadcasting� to appear in Political Communication. 

To replicate all analyses for in the paper and appendix, run the file �master_file.r� after first setting your working directory in that file. This replicates all analyses except Figure A1 in the appendix. To replicate that figure, you need to uncomment a final bit of code in the file �gallup_data_analyses.r� (it runs fine by its own, but not when called from the master file). 

The R code files included in this archive are: 

cces_analysis.r: replicates the CCES analysis in Tables 4 and 5 of the paper 

election_analysis.r: replicates Table A7 in the appendix 

gallup_data_analyses.r: replicates Tables 1-3, as well as tables A5 and A6 in the appendix 

gallup_data_analyses_dma.r: replicates Table A4 in the appendix 

gallup_data_analyses_zip5.r: replicates Table A3 in the appendix 

placement_analysis.r: replicates Table A2 in the appendix 

table_a1.r: replicates Table A1 in the appendix
